Abstract

This study analyzes the incidence rates and regional differences for heat-related illness (HRI) and excess mortality due to heat waves in 2018. The 2018 Korean heat waves caused 44,060 HRI patients and 929 (95% confidence interval: 739~1,143) mortality. The incidence rate of HRI was 8.5 per 10,000 people, which is 1.4 to 2.7 times higher compared to the previous years (2011-2017). The excess mortality rate in 2018 was 1.79 per 100,000 people, which is 2.2 to 6.9 times higher than the previous period. The incidence rate of HRI in rural areas was about 2 times higher than that in the urban areas. The excess mortality rate in rural aras also was higher than in urban areas. The results show that the heat wave of 2018 had a serious impact on public health. In addition, the results suggest that it is necessary to strengthen strategies and policies to prevent the negative health impacts of heat waves in rural areas.

본 연구는 2018년 폭염으로 인한 온열질환자와 초과사망자의 발생률과 그 지역적 차이에 대하여 분석하였다. 2018년 우리나라에서는 44,060명의 온열질환자와 929명(95% 신뢰구간: 739~1,143명)의 초과사망자가 발생하였다. 2018년의 온열질환자 발생률은 8.5명/만명으로 이전 기간(2011~2017년)에 비해 1.4~2.7배 높았다. 2018년의 초과사망률은 10만명당 1.79명으로 이전 기간에 비해 2.2~6.9배 높았다. 농촌의 온열질환 발생률은 도시에 비해 약 2배 높았고, 초과사망률 역시 농촌에서 더욱 높게 나타났다. 본 연구 결과는 2018년의 폭염이 공중 보건에 심각한 영향을 미쳤다는 것을 보여준다. 또한 농촌 지역에 대한 폭염 대응 정책이 강화될 필요성이 있음을 시사한다.
